Summary of what the patchset does:

- 1 -> clean up that messy code somehow
- 2 -> make so you have the buffering/clustering cut predictable
- 3 -> make sure you flush before you got a keyframe

This way you always know if the cluster you got has a keyframe since it
is the one next the one you got after feeding a keyframe packet to the
muxer.

The simplest way (lazy I know) to always get a cluster that the browser
can grock is simply set the time and size limit to a huge value so it is
always a keyframe one.
